PIPE-WRENCH.

Specification of Letters Patent.

Patented J une 9, 1914.

To all whom it may concern Be it known that I, I-IENRY J. BALLEM, acitizen of the United States, and a resident of Winthrop, in the countyof Suffolk and State of Massachusetts, have invented a new and usefulImprovement in Piperenches, of which the following is a specification.

My invention relates to pipe-wrenches and its objects are to improve theconstruction of such wrenches in the manner hereinafter set forth and toprovide an attachment whereby the wrench may be employed as apipe-cutter.

My invention will be described by reference to the drawings whichaccompany and form a part of this specification; but it will beunderstood that various modifications may be made in the particularconstruction illustrated without departing from the spirit of myinvention.

In the drawings, Figure 1 is a side view of my improved wrench, showingthe position of the parts when the device is used as a pipe-cutter. Fig.2 is a plan view and Fig. 3 is a side view showing the position of theparts when the device is used as a wrench.

In the particular drawings selected for more fully disclosing myinvention, 1 represents the outer jaw of a pipe-wrench having the usualserrated inner face and cast integral with the rectangular shank 2. Theinner jaw 3 having a similar serrated face, is provided with a socket 4to receive the shank 2, said socket being large enough to permit ofrelative motion in the plane of the jaw between said jaw and shank, andis connected with the threaded stock 5 by means of the pin 8 passinghorizontally through the jaw and cooperating with the groove 6 milledinto the extension 7 of said stock, so that the latter is capable ofrotary, but not longitudinal, motion with respect to the aw 3 wherebythe rotation of said handle will move the inner jaw with respect to theouter.

The band 9, which is in threaded engagement with said stock is providedwith asocket 10 for receiving the shank 2, and a pin 11 holds the latterin pivotal engagement with said band, said socket, as shown, being largeenough to permit of a certain amount of play between the stock and band.A spring 12 is provided to normally hold the inner jaw away from theshank 2, and in the present instance one end of said spring is securedto the upper wall of the socket 4 and the other end is in engagementwith the shank. It willbe obvious that any suitable means may beemployed for providing for relative motion between the inner jaw and theshank and also for normally holding the former away from the latter.

By means of the handle 20, preferably integral with the screw-threadedstock, the

inner jaw may be adjusted against the pipe or other cylindrical memberto be rotated.

In order to adapt the wrench to use as a pipe-cutter, I pivotallyconnect to one of the jaws a shield 14 and to the other a cutterblock17, having a rotary cutter 18 mounted therein by means of the pin 18. Inthe present instance the shield 14 is shown pivoted to the outer end ofthe outer jaw by means of the link 13 and the cutter-block is shown aspivoted to the outer end of the inner jaw by means of the links 16, 16,although it will be understood of course that if links are employed forpivotally attaching the shield and cutter-block to their respectivejaws, a single link may be used to connect the cutter-block and theinner jaw and a double link to connect the shield to the outer jaw. Itwill also be obvious that the relative positions of the shield andcutter-block may be reversed and that if desired, a cutter-blockidentical with that shown at 17 may be substituted for the shield 14.When the device is being used as a wrench, the shield and cutter-blockare turned back as shown in Fig. 3, and in such case, if desirable, theymay be held intheir inoperative respective positions by the spring-catch15, which snaps over the end of the shield and the spring-catch 19 whichsnaps over a projection on the cutter-block, such for example, as theend of the pin 18', the cutter 18, when the cutter-block is in itsinoperative position fitting into the recess 3 in the inner jaw 3.

When the wrench is used as a pipe-cutter, it is desirable to provide ahand-grip to furnish the necessary leverage for turning the handle andthreaded stock to force the cutter into the pipe prior to rotating thedevice around the pipe. For this purpose I provide a member 21 arrangedto be received in the pocket 22 of the handle and held therein by thespring-catch 23 which engages one end thereof, the other end being bentas shown at 24 and shaped to pass through the hole 25 and fit snuglyagainst the inner wall of the opposite pocket 22.

When in use as a grip, the rod 21 is passed through the hole 25 so as tolie in a plane transverse to the longitudinal axis of the handle asshown in Fig. 2.

In order to extend the length of the handle, the threaded end 27 of thehand-grip may be screwed into the threaded end 26 of the handle.

I claim:

1. A wrench having jaws, each provided with a, serrated inner face, ashield, a link pivotally connecting said shield to the outer end of onejaw, a cutter-block, a link pivotally connecting said cutter-block tothe outer end of the other jaw, said cutter-block being provided with agroove, and a cutter pivoted to said cutter-block and partially Vinclosed within said groove, the jaw to which said cutter-block ispivoted being provided wit-ha cooperating recess for housing Gopies'ofthis'patent may be obtained for said cutter when said cutter-block is inits inoperative position.

2. A wrench having jaws, each )rovided with a serrated inner face, ashiel a link pivotally connecting said shield to the outer end of onejaw, a cutter-block, a link pivotally connecting said cutter block tothe outer end of the other jaw, and a cutter pivoted to saidcutter-block, the jaw to which said cutter-block is pivoted beingprovided with a recess for housing said cutter when said cutter-block isin its inoperative position.

In testimony whereof, I have hereunto subscribed my name this 20th dayof September, 1913.
